bule car diaphragmsi ifiled April 24,1916,

This invention relates to an improved type of metal vestibule car diaphragmwherein a constructionis utilized to pernnt BX- panding movement of the diaphragm with reference to the car on which it is attached, and with means forming'a part of the construction for providing a weather proof seal at the roof structure of the dia phragm and in. movable connection therewith to the car. i

It is an object therefore'of this invention to providein combination with a metal car diaphragm construction utilizing parts adadjustably associated to permit expansion {and contraction ofthe diaphragm with re 'spect to the car, of a seallngmeans to seal the connection of the diaphragm along the roof portion thereof at the point of connection with the car to insure weather proof passage on the interior of the diaphragm.

It is also an object ofthis invention to construct in combination with a metal car diaphragm comprising a stationary and movable section, m'eans associated with the car'and co-acting with the movable section to afford a sealjat the point of connection thereof with the stationary section to insure a weather proof passage through the diaphragm on the interior'thereof.

It is furthermorean important object of this invention to provide a sealing means for a telescoping car diaphragm to insure a weather proof'connection between the parts of thediaph'ragm in all positions of adjustment and 'vided with mounted beneath the shown) ls'a channel 2, forming the front 3, is also provlded, comprising a attached upon the variations in movement thereof.

It is finally anobject of this inventionto construct anadjustable car diaphragm prosin1ple and efficient sealing means.

The invention (in a preferred form) is illustrated in the drawings and hereinafter morefully described.

In the drawings:

F ig. 7 is a detail section taken online 77 of Fig. 5. i

a As shown in the drawings:

The reference numeral 1, indicates as a whole the end of a car, and movably platform thereof (not member of a platform buffing mechanism of any usual and well known construction secured and supported on which is a vestibule diaphragm face plate 3. As clearly shown in Fig. 1 an auxiliary buiiing mechanism for the upper end of the face plate I horizondirected rod 45, securely rear surface of the face plate 3, extending rearwardly and slidablv through certain frame members of the car body. and having a compression spring 5. coiled thereabout, adapted to resist inward slidingmovement of said rod with similar tally rearwardly movements of the face plate and vestibule diaphragm. Forming a part of the car confront surface of the. vertical frame plate 7,

and projecting outwardly therefrom in parallel relation to the gabled top or roof plate 6, and of less width than the plate6, is another gabled plate 9, which is flanged downwardly at its side and forward margins, and attached to a horizontal ceiling plate 10, of the vestibule of the car, affording a compartment through which the associatedrod 4:, and spring 5, extend. I

Secured in upright position on each side of the end ofthe car body are large chan- 7 nels, having an inner wall 11, and an outer V r resilient sidewalls 21 22, to thefface plate wall 12, with the forward or outer margins of said respective walls flanged outwardly as clearly shown in Fig. 3. Provided upon each side of the car body are upright I- beams 13, and the respective channel mem;

bers 11--12, of the vestibule diaphragm are secured thereto by angle irons 11 and 15, re-

spectively, riveted to the flanges of said I- beams and to the side walls 12, of the channel members.

The elements of the movable section of the diaphragm are connected upon the face plate.

3, and for this purpose a rearwardly tapered gabled roof plate member 16, is flanged at its forward margin and riveted to the rear surface of said face plate, as clearly shown in Figs. 1 and 2, and extends rearwardly beneath thegabled topplate 6, and over the gabled top wall of the compartment or abutment member 9. Near its side margins, guide or abutment members 17, of trapezo dal section, as shown in Fig. 2, are provided, each consisting of a plate bent ion gitudinally into trapezoidal form and rivetedor brazed beneath the surface of the roof plate '16, near the side margins there-of,

' therebetween.

and spaced therefrom to afford a recess Slidably inserted in the recess above the trapezoidal abutments are wing plates 18, which, at their forward ends are connected by means of a pivot. 19, to the roof plate 16, and each provided with a downwardly extending flange, the rear end of which fits slidably within the channels of the stationary diaphragm section, as clearly shown in Figs. 1 and 5.

As shown in Fig. 5, the top horizontal .marginof the outer wall 12, of the channel 11l2, merely extends upwardly to afford 'vergent walls 21 and22', respectively; integrally connected ma rounded bead portion 23, and with .the rear-margins of. said, respective wall members provided with strips 0 of sealing material 24, whicln vowitig 'to the resiliency of the wall members 21 and 22,

are thrust into sealing contact with thein; terior surfaces of the channel walls- 11 and 12. The upper margins of the wallmem- '5 bers 2 2,areturned horizontally. inwardly and provided with sealing strips 20,,which bear upwardly beneath the flat surfaces. of.

the trapezoidal abutment members 17, of the roof plate 16... 1 Forthe purpose of-'. attachment of said 3, a pair of plates 25 and 26, are bolted onthe rear surface oftheface platewith the" margins thereof curved, as clearly shown in Fig. 3, to afford a cylindrical recess within which the rounded or beaded portion 23,.of sa d divergent wall'members 21.and 22, fits. andis capable of movement th'erein.-

A sealing mechamsm-1sprovidedfor the roofplate 16,at the point at which the same slides inwardly within} the car end beneath the gable top plate 6, 'and for this purpose,- as clearly shown in Figs. 1 and 7, a' pair of angled plates 30 and 31, respectively, are secured in inclined position on the built-up end plate member 8, of'the car :projecting outwardly therefrom. with their lower margins spaced from. oneanother and having mounted therein a sealing str1p32, normally impelled downwardly into contact with. the topsurface ofthe gabled'roof plate'l5,"by springs 33. p 5 The operation isas follows Due to'the flexible connection on the face plate 3, to the side wall members 21- 22, of themovable diaphragm section, a flexing or weaving movement between thesame is. readily permitted and furthermore,- owing to the fact that norigidconnection exists s between the gable roofplate 16, of the movable diaphragm section and the side walls 21- 22, thereof, adjustments ,With respect' thereto due to variations in movementofthe diaphragm withrespectto the car, are also readily permitted. ,1 he telescoping movement of the movable diaphragm section composed of the sidewalls 2l-22,' and*roof' plate. member 1 6,-are readily permitted, owing to the fact that the' resilient side wall members 21-22, telescope within the fixed upright channel members 11l2, of the stationary diaphragm section, and the roof plate member 6, sliding beneath the sealing strip 32, provided at the upper end of the car. v

A certain angular movement of the face plate 3, with respect to the elements of the movable diaphragm section is permitted, and when such movement takes place, of course, the face plate has a hinged action on the cylindrical or beaded portions 23, of the side walls 2122, but the gabled roof member 16, moves as a unit therewith, and owing to the fact that the side margins thereof are tapered inwardly, as shown clearly in Fig. 6, the same is capable of swinging laterally with respect to the elements of the stationary diaphragm section. A seal between the gabled roof plate member 16, of 'the movable diaphragm section and its side walls 21 -22, is efiected by the pivotally mounted wing plates 18, which engage in the recess provided therefor beneath the side margins of the roof plate 16, and are turned downwardly to overlap the upper edge of the side Wall members 22. As a consequence, when the swinging movements of the roof plate nrember 16, take place as the vestibule face plate 3, is caused to assume an angled position, the wing plates maintain substantially the same relation with the side wtills 2122, and the roof plate 16, slides with reference thereto. the seal, however, being always maintained, and when the associated roof plate 18 and wing lates 18, move inwardly with respect to the stationary diaphragm section, said wing plates 18, engage within the channel members 11-12, contacting the inner surface of the walls 12.

I am aware that various details of construction may be varied through a wide range without departing from the principles of this invention, and I therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

I claim as my invention:

1. The combination with a telescoping metal car diaphragm of spring impelled means mounted on the car and co-acting with the diaphragm to afford a seal between the same and the car.

2. The combination with a. telescoping metal car diaphragm of spring impelled means mounted on the end of the car and co-acting with the roof portion of said diaphragm to afford a seal between the diaphragm and'the car.

3. The combination with a telescoping car diaphragm of spring impelled means independent of the diaphragm co-acting with a movable portion thereof to afford a seal be tween the diaphragm and the car to which it is attached.

4. The combination with an apex type of telescoping metal car diaphragm of resilient means mounted on the car and contacting the apex roof member of the diaphragm to afford a seal between the same and the car.

5. The combination with an apex type of diaphragm of resilient means mounted on the car co-acting therewith to afiord a seal between the diaphragm and the car.

6. The combination with a car diaphragm one part of which is movable, a downwardly opening channel member secured to the car, a sealing strip movable in the channel and bearing against the movable roof member to afford a seal, and springs in the channel member yieldingly holding the sealing, strip against the movable roof member.

7. In a metallic diaphragm roof construction, the combination with metallic telescoping roof sections, and a sealing mechanism attached to the car above the roof sections and bearing on the top of one of the telescoping sections.

8. A sealing device for a metal roof diaphragm comprising in combination with the telescoping roof sections, a channel member secured rigidly on the car and a spring pressed sealing means in said channel.

9. The combination with a telescoping metal car diaphragm, of a longitudinally slidable roof member capable of lateral swinging movement, and sealing means yieldably mounted upon the car to bear upon the exterior surface of said member, and permit longitudinal sliding and lateral swinging movements thereof to take place, affording a seal therealong.
